In this April 11, 2011 file photo, Brigitte Nielsen launches her new book "You Only Get One Life" at Earls Court in London, England. The Danish model is expecting her first child with husband Mattia Dessi.

Brigitte Nielsen is rocking a baby bump.

The 54-year-old Danish model, actress and reality TV star has revealed she is expecting her fifth child. In two photos shared to her Instagram account, Nielsen posed with her prominent baby bump taking center stage.

"Family getting larger #me #family #brigittenielsen #babybump," she captioned the first shot of herself cradling her bump. "Happy time positive vibes #happyness #positivevibes," the star described the second similar snap.

During her relationship with ex-fiancé Mark Gastineau, Nielsen gave birth to her second son, Killian Marcus Gastineau. She welcomed two more sons, Douglas Aaron and Raoul Jr., with fourth husband Raoul Meyer.

Nielsen later famously wed Sylvester Stallone, though the marriage lasted less than two years. She also made headlines with her reality TV romance with rapper Flavor Flav after the two met on VH1’s "The Surreal Life."

Her current pregnancy news has inspired fans and followers who are also looking to have children later in life. "Nobody has the rights to lead your own decision unless you allow them to do so," Nielsen responded to one fan who called her an inspiration. "You're the only one in charge of yourself and your own happiness. Best of luck!"
